Grateful Dead - Monkey and the Engineer (alternate live version) lyrics

Once upon a time there was an engineer Drove a locomotive both far and near Accompanied by a monkey that would sit on a stool Watching everything the engineer would do One day the engineer wanted a bite to eat He left the monkey sitting on the driver's seat The monkey pulled the throttle, the locomotive jumped the gun And did 80 miles an hour down the mainline run Big locomotive right on time, big locomotive coming down the line Big locomotive No. 99, left the engineer with a worried mind The engineer called up the dispatcher on the phone To tell him all about his locomotive was gone Dispatcher got on the wire, switch operator to the right Cause the monkey's got the main line sewed up tight The switch operator got the message on time Said there's a Northbound livin' on the same main line Open up the switch I'm gonna let him through the hole Cause the monkey's got the locomotive under control Big locomotive right on time, big locomotive coming down the line Big locomotive No. 99, left the engineer with a worried mind
